The Sightmark Wraith HD is a day night digital rifle scope with the ability to present a target in full colour imagery. During the day, the Wraith can work just like a normal optic with added digital features. At night, the Wraith is able to provide night vision capabilities in two alternative view modes which allow for illumination with IR light. A product with a definite market for anyone interested in mid-range plinking and hunting regardless of the time of day.
Most optics are priced in relation to their features and how reliable they are advertised to be with different calibres and usage. A good compact economically priced optic would be around £150~ where as a high quality brand such as Aimpoint would price their variation at just over £500. The Firefield Impulse 1×22 Compact Red Dot Sight is priced at just under £80 with features that are similar to but do not supersede other more expensive brands.
